Best iPaaS for API Unification

API unification addresses the complexity of integrating multiple third-party APIs by providing a standardized interface, allowing integration logic to be written once for all providers. Integration platforms as a service (iPaaS) facilitate this process by offering the necessary infrastructure and tools. The text reviews top iPaaS options, each with distinct features and limitations. Nango, an open-source platform, offers full flexibility and control, allowing teams to create custom unified APIs. Merge provides pre-built unified APIs for quick deployment but lacks customization. Workato specializes in workflow automation with a visual builder but doesn't support unified APIs. Prismatic offers both low-code and code-first integration options but also lacks unified API support. Choosing an iPaaS depends on specific needs, team capabilities, and the goal of balancing development speed and functionality. The guide emphasizes that while unified APIs are beneficial for secondary integrations, direct integrations may be preferable for critical functionalities requiring deep, API-specific capabilities.
